Person Detection on Raspberry Pi Pico with ArduCAM and TensorFlow Lite

ArduCAM is popular for camera-based applications with various boards ranging from Arduino to Raspberry Pi. We also saw the company’s tiny coin-sized Raspberry Pi compatible module 5 years ago. Now, it also supports the newly launched Raspberry Pi Pico for real-time video applications. Raspberry Pi Pico is compatible with the ArduCAM Mini 2MP Plus camera featuring an OV2640 2MP CMOS image sensor that supports automatic image control functions including Automatic Exposure Control (AEC) and Automatic Gain Control(AGC). The camera also comes with an onboard JPEG encoder for image compression. The company has provided a Github repository with two demo applications: a video streaming application and an example for basic person detection with the probability percentage of detection. There is also an option of directly using the UF2 files for flashing with Raspberry Pi Pico, if you don’t want to build the demo from the source code yourself. The application runs […]

Deutsche Telekom IoT Gateway combines LoRaWAN and LTE-M

I’d normally view LoRaWAN and LTE IoT standards such as NB-IoT or LTE Cat-M (aka LTE-M or eMTC) as competitors, but The Things Industries and Deutsche Telekom partnered to launch an IoT gateway with both LTE-M and LoRaWAN capabilities together with associated services. We do not have much information about the hardware, but it is a LoRaWAN gateway designed by MikroTik that connects to an LTE-M backhaul and to The Things Industries’ device and data platform. If the picture above does indeed represent the actual gateway it should also be equipped with two PoE capable Ethernet ports, and an RS485 terminal block, plus a USB port and a SIM card slot. The solution would mostly be used for smart buildings at first taking advantage of the superior signal penetration of LTE-M. Sensors would send data to the LoRaWAN gateway which then, would forward it to the cloud over LTE-M. This […]

Open hardware Raspberry Pi Pico VGA, SD Card, and Audio demo board to support QVGA video playback

Abhishek recently posted an overview of Raspberry Pi RP2040’s two PIO blocks with examples in C and Micropython using some PIO assembler code. He used some basic examples like blinking an LED, but the Raspberry Pi Foundation also mentioned the programmable IO could be used to drive a VGA display, read and write data from a MicroSD card at reasonable speeds, and so on. However, the Raspberry Pi Pico does not have any of those interfaces, and it would be nice to have a board that does. It turns out there’s such a board in “Chapter 3. The VGA, SD Card & Audio Demo board for Raspberry Pi Pico” of “Hardware Design with RP2040.pdf” document. It will be sold as the “Pimoroni Pico VGA Demo Base” board for 19.50 GBP inc. VAT (about $22 US ex. VAT), but since the KiCad hardware files are open-source, I’d assume other companies may […]

Ubuntu Core 20 released for secure Linux IoT devices and embedded systems

Canonical has just released Ubuntu Core 20, a minimal, containerized version of Ubuntu 20.04 LTS for IoT devices and embedded systems. The company highlights several security improvements and features of the new version of the Linux-based operating system with secure boot, full disk encryption, secure device recovery, and secure containers. Ubuntu Core 20 is said to come with all benefits from Ubuntu 20.04 LTS such as regular, automated updates, the ability to manage custom app stores, and offers a longer 10-year support window. Ubuntu Core is available and certified on popular32-bit and 64-bit x86 and Arm single board computers such as Intel NUC or Raspberry Pi 4. Minimum requirements include a single-core processor @ 500 MHz, 256MB RAM, and 512MB storage. Alternatively, it’s also possible to run it in a virtual machine on your PC. Security is further enhanced with apps running in containers, and since only the necessary software […]

LoRa 2.4GHz is now supported by The Things Network

Semtech brought LoRa to 2.4 GHz through their SX1280 & SX1281 transceivers to enable hardware manufacturers to design region-independent products, rather than region-specific products in the 433, 868, and 915 MHz bands a few years back. Things Industries announced support for LoRa 2.4GHz in The Things Network community network and its open-source stack at The Things Conference 2021 last week. However, switching to 2.4 GHz has a cost since range, one of the key selling points of LoRa, will be reduced compared to sub-GHz frequency, and that makes it most suitable for applications that work in different regions such as maritime and intercontinental logistics applications. Wilhelmsen has partnered with The Things Industries (TTI) and selected Semtech’s LoRa devices as the foundation for its new global 2.4GHz maritime IoT of the Seas platform to deliver an ecosystem of cost-effective, robust and proven IoT solutions and make them available to its diverse […]

MutantC v3 open hardware DIY UMPC works with Raspberry Pi and compatible SBC’s

FOSDEM 2021 open-source developer event will take place online later this week, and yesterday we compiled a list of talks, with one entitled “MutantC PDA introduction – open source and hardware PDA shell” piquing my interest. The talk will be about the third revision of the hardware which allows you to create your own UMPC or handheld computer powered by a Raspberry Pi SBC or other compatible single board computers including Asus Tinker Board S, PINE H64 Model B, Banana Pi BPI-M4B, among others. MutantC v3 is versatile and highly customizable as can be seen from the specifications highlights: Supported SBCs – Raspberry Pi Zero, 2, 3, 4 and compatible. Arduino for keyboard – SparkFun Pro Micro 5v/16Mhz or SparkFun Qwiic Pro Micro – USB-C Display – 2.8-inch, 3.5-inch, or 4-inch “GPIO” LCD such as AdaFruit PiTFT 480×320 display Custom PCBs for display, mainboard, and thumbstick Expansion External 12-pin “docking” […]
